Testing's Purpose
Captions available
The idea
Testing verifies that software delivers on the project's requirements without unintended errors or side effects — confirmation that the software does what it was expected to do.
In practice
A dosage calculator is tested against what the clinic specified, not what the code happens to do.
Where people slip
The requirements are the standard; testing the wrong thing proves nothing.
